I am currently driving a BMW F06 650i xDrive 4.4L with the following winter wheels: Rims: 4 x Original BMW 8.5×19 EH2+ ET 25 (VA + HA identical) Tires: 4 x Dunlop Winter sports 5 255/40 R19 100V XL (VA + HA identical) I want to get the summer rims and tyres now, but I’m not sure if you’re with the current car settings ( suspensions, tachoeichung etc.): Rims (VA): 2 x Original BMW 703M 8.5×20 ET 33 Rims (HA): 2 x Original BMW 703M 9×20 ET 44 Tires (VA): 2 x Summer tire Dunlop SP Sport Maxx GT* RSC 245/35 R20 95Y Tyres (HA): 2 x Summer tire Dunlop SP Sport Maxx GT* RSC 275/30 R20 97Y BMW recommends this summer wheel constellation for my specific car. My question now is whether the F06 recognizes that other, but also approved, wheels are installed and automatically adapts to these new wheels, or if there are problems, which should mean that you have to make additional adjustments on the car (adjust suspensions, tacho The “wheel size calculator” shows the following differences with regard to the VA tyres/wheels combinations:https://www.wheel-size.com/…/?… Among other things, the side wall height changes with respect to the front tyre by 16%, the circumference decreases by 1% and the weight increases by 0.6 KG.https://www.wheel-size.com/…/?… In the rear axle the values are a bit different again. *Bonus question: BMW officially recommends the star The Dunlop SP SportMaxx GT is the only one that can be considered. Would I be so much worse off with a Goodyear Eagle F1 Asymmetric F6? The SportMaxx does even worse in tests than the cheaper Eagle, yet there is no star from BMW…
